"On the other hand, Poland is now reshaping its approach to its energy policy. If the decision is internally taken to move towards a low emission economy, Poland and other central European countries, with substantial support of EU money, can become leaders in energy transition as their economies will require massive investment in clean energy generation," he said.
Energy and climate change expert Paul Rice of Pinsent Masons said that the UK, which is also targeting 'net-zero' emissions by 2050, would be watching the debate with interest.
"It is clear that the European Commission sees this as the right time to drive a 'green recovery' across all sectors of the economy, believing that the overall cost of inaction will be significantly higher," he said. "Also, it sees this as a point of competitive advantage for EU companies."
"Interestingly, in the European parliament, there are factions pushing for an even higher emissions reduction target and the 55% reduction has been widely supported. However, they will likely see challenges from EU countries where energy intensive industries feature heavily. But the proposals make clear the scale of the Commission's ambition and it seems likely that the sort of policies covered in the earlier leaked document will form part of the EU's plan to use its coronavirus recovery budget to drive a sustainable and 'climate neutral' economy," he said.
"It will be interesting to see the reaction of the UK government and whether carbon reduction becomes a true cornerstone of the UK's recovery plan, as raised by the Committee on Climate Change in its most recent progress report to the UK parliament," he said.
